  　　About rechargeable lead-acid batteries

  　　Rechargeable batteries were invented decades after the appearance of original batteries. There are several chemicals that can be used to make rechargeable batteries, but many larger models use a combination of lead and sulfuric acid. Rechargeable batteries have the ability to charge when exposed to reverse current. The volume of rechargeable batteries is very powerful, accounting for nearly half of global battery sales.

  　　Flooded rechargeable batteries, also called wet batteries, are closest in design to Daniel's original batteries. These batteries contain a liquid combination of water and sulfuric acid. They are generally more expensive and have a longer lifespan than the Sealed 12v Battery.

  　　Flooded rechargeable batteries obviously require higher maintenance than sealed batteries. Since rechargeable batteries filled with water contain liquid, they must be oriented correctly and may be damaged by strong movement (for example, excessive shaking).

  　　In addition, since they contain some water, a Sealed 12v Battery filled with water requires regular maintenance to maintain the correct liquid level. In extreme climates, their lifespan will be shortened because the water in them will evaporate or freeze. Since water will eventually evaporate even in the mildest weather, rechargeable batteries filled with water can only be used with proper ventilation.

  　　Despite these needs, flooded rechargeable batteries are still the best choice for backup power applications. They are also widely used in backup power sources, utilities, telecommunications, and grid energy storage, and backup power sources.
